I was running the tests on cygwin but I encountered some difficulties:

1) suddenly, the test procedure stopped working (since somewhere between the 2nd of April 16h53 +0000 and the 3rd of April 8h45 +0000); I get the message below when building process_jam_log (I suspect
something related to the definition of BOOST_FILESYSTEM_NARROW_ONLY),

2) I was running the tests on a USB FAT32 external disk and each time I wanted to perform a full test (i.e. not incremental), it took so much time to download the trunk that I posted on the list and
was answered that it was not supposed to run on that type of disk...

so I decided to stop running the tests. If it is possible to find what's wrong in the test procedure with cygwin, I can restart testing but still with my USB FAT32 disk.
